aureolus (Latin)
Where does "aureolus" come from?
The Latin adjective 'aureolus' formed as a diminutive of 'aureus', meaning 'golden' or 'gilded'[1]. This base word itself derives from 'aurum', meaning 'gold'[1][2]. The root traces further back through Proto-Italic '*auzom' to the Proto-Indo-European '*h₂éws-o-m', connected to the root '*h₂ews-' meaning 'to dawn, become light, become red'[3].
Open questions
- The exact Proto-Indo-European reconstruction is uncertain, with '*h₂éws-o-m' considered more likely than the alternative '*h₂é-h₂us-om'. [3]
